• ~; <br />3.3 BATCH TESTING: <br />(Please Hold Testing until a rove has <br />been issued) <br />SAMPLES TO BE TESTED: L396.4 - 2.0 S: L396.4 - 2:1 S <br />Obtain two sub-specimens from each of the tailings specimens <br />ileached and unleached). Use one set of sub-specimens to determine <br />oven dry moisture contest i (based on oven dry weight of ¢~aterial). <br />The second set of wet sub-specimens rill be used for batch testing. <br />Determine the calculated oven dry xeight of the wet sub_specimens <br />by using the following equation: <br />Ys = Yws /.(1 + IMICi ! 100) <br />Where: Ms = Calculated oven dry weight of soliids <br />Yxs = Yeight of wet specimen <br />M/C t = Moisture Content based on oven d~y weight <br />of moisture content specimen <br />Perform EPA Method 1312 (Synthetic precipitation leach test <br />for soils) using Extraction !laid il. Place the xet tailings <br />specimen,; in a container such that the batch test xhen m xed will <br />have a zero hEad space. Base the amount of solids to be us~d on the <br />calculated oven dry Height of the specimens. <br />Ail~x the solids to settle then decant and filter the leachate. <br />Test for the following parameters: <br />pB, Conductivity, Major Cations (Calcium, Magnesium, P caesium, <br />Sodium), Major Anfons (Alkalinity, Ammonia, Bicarbonate, C rbonate, <br />Chloride, Fluoride, Sulfide, Nitrate, Nitrite, Sulfate Total <br />Dissolved Solids, Total, :'ree sad Y.A.D. Cyanide, plus Che ollowing <br />dissolved metals: <br />Aluminum, Araeaic, Barium, Boron, Cadmium, Chromium (total), <br />Copper, Iron, Lead, Manganese, Mercury, Molybdenum, Nickel, <br />Selenium, Silvet, Ziac. <br />• <br />
